Search engines discover and store information about documents such as web pages, which they typically retrieve from the textual content of the documents. The documents are sometimes retrieved by a crawler or an automated browser, which may follow links in a document or on a website. Conventional crawlers typically analyze documents as flat text files examining words and their positions (e.g. titles, headings, or special fields). Data about analyzed documents may be stored in an index database for use in later queries. A query may include a single word or a combination of words.
Dynamic reports are documents or portions of the content a document created at runtime. Each time a dynamic report is run, up-to-date data is gathered from a data store and provided to a local computing device executing an application that renders the dynamic report. Typically, the report definition, which remains the same over time, is stored at the local computing device. In contrast, static reports are commonly generated based on retrieved data that is stored along with the report definition (e.g. report parameters) at the local computing device.
Traditional search engines such as the ones discussed above retrieve document contents and index them as plain text. Thus, the data in dynamically generated reports may not be parseable or indexable for a conventional search engine. This may be especially true when the dynamically generated report is non-textual such as a chart, an image, or a video content.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to exclusively identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter.
Embodiments are directed to parsing and indexing of dynamically generated reports. Upon detection of a dynamically generated report, a data source for the dynamically generated report may be identified based on metadata or other information associated with the report. Crawleable or machine readable metadata and data may be generated using the data source such that data represented in the report and/or other relevant data from the data source can be indexed and searched.
These and other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are explanatory and do not restrict aspects as claimed.
As briefly described above, dynamically generated reports may be detected and a data source for the dynamically generated report may be identified based on metadata or other information associated with the report. Machine readable metadata and data may be generated using the data source such that data represented in the report and/or other relevant data from the data source can be indexed and searched. In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustrations specific embodiments or examples. These aspects may be combined, other aspects may be utilized, and structural changes may be made without departing from the spirit or scope of the present disclosure. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
While the embodiments will be described in the general context of program modules that execute in conjunction with an application program that runs on an operating system on a personal computer, those skilled in the art will recognize that aspects may also be implemented in combination with other program modules.
Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that embodiments may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, and comparable computing devices. Embodiments may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
Embodiments may be implemented as a computer-implemented process (method), a computing system, or as an article of manufacture, such as a computer program product or computer readable media. The computer program product may be a computer storage medium readable by a computer system and encoding a computer program that comprises instructions for causing a computer or computing system to perform example process(es). The computer-readable storage medium can for example be implemented via one or more of a volatile computer memory, a non-volatile memory, a hard drive, a flash drive, a floppy disk, or a compact disk, and comparable media.
Throughout this specification, the term “platform” may be a combination of software and hardware components for managing computer and network operations, which may include searches. Examples of platforms include, but are not limited to, a hosted service executed over a plurality of servers, an application executed on a single server, and comparable systems. The term “server” generally refers to a computing device executing one or more software programs typically in a networked environment. However, a server may also be implemented as a virtual server (software programs) executed on one or more computing devices viewed as a server on the network. More detail on these technologies and example operations is provided below.
Search engines employ a variety of methods to rank the results or index them based on relevance, popularity, or authoritativeness of documents compared to others. Indexing also allows users to find sought information promptly. When a user submits a query to a search engine (e.g. by using key words), the search engine may examine its index and provide a listing of matching results according to predefined criteria. The index may be built from the information retrieved from the contents of the crawled document and/or user data and the method by which the information is indexed. The query may include parameters such as Boolean operators (e.g. AND, OR, NOT, etc.) that allow the user to refine and extend the terms of the search.
As discussed previously, dynamic reports are created at runtime gathering data from a data store. The data store may be on the same computing device as the application rendering the report or on a different computing device connected through a network. The report may present a portion (or whole) of the available data from the data store textually or graphically. The report may even be in video format (e.g. a time dependent report that presents changes in selected data). Thus, the underlying data is typically not available in textual format from the report itself. Indeed, the report may not even include keywords or search terms that are being used to perform a search.
A search engine according to embodiments enables enhanced indexing and searching detecting a report type, determining a data source associated with the detected report, retrieving the underlying data from the data source, and rendering the dynamic report machine-readable, thereby searchable employing keywords or search terms. The information extracted, organized, ranked, and annotated may be indexed and stored for caching and faster retrieval when searched by a user.
In the example system of diagram 100, user 102 may interact with a variety of networked services through their client 104. Client 104 may refer to a computing device executing one or more applications, an application executed on one or more computing devices, or a service executed in a distributed manner and accessed by user 102 through a computing device. In a typical system client 104 may communicate with one or more servers (e.g., server 112). Server 112 may execute search operations for user 102 searching documents on server 112 itself, other clients 106, data stores 108, other servers of network 114, or resources outside network 110.
In an example scenario, network 110 may represent an enterprise network, where user 102 may submit a search request. A search application on server 112 may crawl and evaluate documents detecting dynamic reports and determining associated data sources. The crawled documents and retrieved information may be used to index machine-readable data with additional information from data sources associated with crawled documents. The search may also include resources outside network 110 such as server 116 or servers 122 and data stores 120, which may be accessed through at least one other network 118. The search may be performed on a database source, an analysis service, a portal, another server, and/or a desktop.
The example system in
A search engine according to embodiments (e.g. search engine 226) may find documents that include textual data, graphic data, video data, tables, images, and similar forms of embedded content. Some of the embedded content (or the entire document) may be dynamically generated reports, which receive their data from an external data source such as data source 224. Document 230 is an example document that includes table 234 (textual data), graphic chart 232, and video data 236. The presented data may not be physically stored along with the document 230 itself. Thus, a conventional flat text search may not detect the dynamic data represented by any of these elements.
In a system according to embodiments, search engine 226 may first detect a type of the dynamic report(s) based on metadata associated with a portal publishing the document or based on a document identifier (e.g. a Uniform Resource Locator “URL” assigned to the report/document). Next, a two-step crawl process may be executed, where a definition of the document is parsed and associated metadata and/or data directly retrieved from the definition first. The second step of the crawl process may include detecting the dynamic rendering part of the document (report) and based on the report type, calling associated web services, custom code/methods/middle tier services, a local report rendering engine, a database, a data warehouse, and/or other data sources to convert the dynamic portion to a machine-readable format.
Search engine 226 may then index crawl results for faster search responses building an index. The search engine may also rank search results based on the types of reports embedded into the document and the retrieved external data, and enable presentation of the additional information when search results are rendered by rendering application(s) 228 such that users can determine importance/relevance of a document for their search.
Differently from
According to some embodiments, document 230 may be a business intelligence document such as spreadsheet document, dashboards, or scorecards that contain tables, charts, reports, diagrams, filtered charts/tables, and similar elements. Some of these elements may be generated by an application other than the spreadsheet application associated with the spreadsheet document and embedded into the spreadsheet document statically or dynamically (i.e. element data residing at an external source). The reports (e.g. charts and/or diagrams) may be generated based on filtering data available from middle tier service 340 or data sources 224. Thus, the reports in document 230 may not reflect the entire extent of available data.
Since external data may be stored in different data sources such as various databases, servers, tables, and comparable ones, the metadata associated with each data and data storage may be different. Search engine 326 may determine data type associated with each detected report within a document, range of data, and data storage type. Then, crawl operations may be customized to retrieve information associated with each report and data for each report.
Moreover, a user interface of rendering application(s) 228 (or the search engine 326) may be adjusted in accordance with the indexing and ranking strategy, such that search results for different kinds of dynamic reports may be displayed in a unified and consistent manner. For example, data may be categorized as being associated with a chart-based report, a table-based report, a video-based report, and comparable ones, and search results may indicate each result's category textually and/or graphically.
According to an example scenario displayed in diagram 400, document 446 may include a dynamically generated report 450 based on data from external data source 444. While the data (452) stored in data source 444 may be based on example parameters X, Y, and Z, the dynamic report 450 may present data based on parameter X only (e.g. data source may store sales data for worldwide activities by country and the report may only display a chart based on North American sales). Search engine 426 crawling documents in preparation for a search request from user 442 may find document 446, detect a type of report embedded in the document based on metadata 448 (e.g. identifier) and gather relevant information from data source 444 such that the presented data (based on parameter X) as well as additional available data (based on parameters Y and Z) are made available for searching. Thus, user 442 may be able to retrieve data based on all three parameters, individually or in combination, from data source 444 following the presentation format of report 450 (or in another format) according to embodiments.
For example, search request 454 from user may indicate user's interest in data based on parameter Z. Following the above described operations, search engine 426 may modify the parameter for the dynamic report, and render data based on parameter Z available from data source 444 in search results 456 to rendering application 428. Following the above described example, user 442 may be interested in sales data for Japan. In a conventional search, report 450 may be disregarded because it only presents North American sales data or listed in the results but skipped as irrelevant by the user. A search engine according to embodiments, not only determines that there is more underlying data associated with report 450, but renders that data searchable and limits its scope to the focus of the user's search. Thus, the results of the search for sales data in Japan may bring back a chart similar to the one displayed in report 450 based on sales data for Japan or access to the data in searchable form (again based on sales in Japan). According to other embodiments, the search engine may render the entire data from data source 444 available.
The examples in
Client applications executed on any of the client devices 511-513 may submit a search request to a search engine on the client device 511-513, on the servers 514, or on individual server 516. The search engine may crawl documents with dynamic reports, detect report type(s), call relevant web services or report rendering engines to generate searchable format data based on the report as discussed previously. The service may retrieve relevant data from data store(s) 519 directly or through database server 518, and provide the ranked search results to the user(s) through client devices 511-513. The service may further provide filtering and/or dimensioning of results by modifying filtering parameters associated with the dynamic report(s).
Network(s) 510 may comprise any topology of servers, clients, Internet service providers, and communication media. A system according to embodiments may have a static or dynamic topology. Network(s) 510 may include secure networks such as an enterprise network, an unsecure network such as a wireless open network, or the Internet. Network(s) 510 may also coordinate communication over other networks such as Public Switched Telephone Network (PSTN) or cellular networks. Furthermore, network(s) 510 may include short range wireless networks such as Bluetooth or similar ones. Network(s) 510 provide communication between the nodes described herein. By way of example, and not limitation, network(s) 510 may include wireless media such as acoustic, RF, infrared and other wireless media.
Many other configurations of computing devices, applications, data sources, and data distribution systems may be employed to implement a framework for parsing and indexing dynamic reports. Furthermore, the networked environments discussed in
Application 622 may be any application that is capable of performing search through search engine 624 on other applications/data 626 in computing device 600 and/or on various kinds of data available in an enterprise-based or cloud-based networked environment. Search engine 624 may crawl, index, perform searches, and rank results detecting dynamic reports, determining data sources, and rendering presented data searchable as discussed previously. Application 622 and search engine 624 may be separate applications or an integral component of a hosted service. This basic configuration is illustrated in
Computing device 600 may have additional features or functionality. For example, the computing device 600 may also include additional data storage devices (removable and/or non-removable) such as, for example, magnetic disks, optical disks, or tape. Such additional storage is illustrated in
Computing device 600 may also contain communication connections 616 that allow the device to communicate with other devices 618, such as over a wired or wireless network in a distributed computing environment, a satellite link, a cellular link, a short range network, and comparable mechanisms. Other devices 618 may include computer device(s) that execute communication applications, other web servers, and comparable devices. Communication connection(s) 616 is one example of communication media. Communication media can include therein computer readable instructions, data structures, program modules, or other data. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.
Example embodiments also include methods. These methods can be implemented in any number of ways, including the structures described in this document. One such way is by machine operations, of devices of the type described in this document.
Another optional way is for one or more of the individual operations of the methods to be performed in conjunction with one or more human operators performing some. These human operators need not be collocated with each other, but each can be only with a machine that performs a portion of the program.
Process 700 begins with operation 710, where search contents are crawled for indexing purposes. As discussed previously searches may be performed in a desktop environment, an enterprise-based network, a cloud-based network, or a combination of an enterprise-based network and a cloud-based network. At operation 720, dynamic reports may be detected based on information associated with a portal publishing the document containing the report or an identifier of the report/document.
At optional operation 730, static portion(s) of the document may be parsed and data/metadata retrieved for indexing. At operation 740, a data source associated with the report may be determined from metadata. This may be followed by operation 750, where the underlying data is rendered searchable and indexed. In response to receiving a search request at operation 760, search results based on indexed information may be provided to the requesting user at operation 770.
The operations included in process 700 are for illustration purposes. Parsing and indexing of dynamically generated reports may be implemented by similar processes with fewer or additional steps, as well as in different order of operations using the principles described herein.
