Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. §119(a) of an Indian patent application filed on Apr. 2, 2014 in the Indian Patent Office and assigned Serial number 1782/CHE/2014, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a knowledge network. More particularly, the present disclosure relates to a mechanism for retrieving information for assisting a user using a localized knowledge-based assistive network.

BACKGROUND

Knowledge of a user is expanding exponentially with the number of interactive portals, communities exchanging information constantly over a network. Due to high-level of information exchange between various users across the network, finding relevant information and retrieving the information effectively from the network becomes a challenging task.

In a method according to the related art, information about an expert's profile is stored on a remote server or a database. Further, as the user provides a query for searching relevant information within the network, the expert's profile that is stored within the network is determined and shared with the user in accordance with the search query. Identifying one or more expert's profile within the network consumes a lot of network bandwidth and reduces search efficiency. Further, the expert's profile uploaded in the remote server or the database can be accessed by any user or by a service unknown to the profiled user, which can hamper the privacy and security aspects for the expert profile.

In another method according to the related art, an information source in the form of a knowledge-graph is stored in a remote database and the stored information source can be retrieved by the user by providing a query on a user device. Further, the stored information source is connected with one or more clients based on the query provided by the user. Identifying the information source based on the query within the network can increase the network bandwidth usage. Further, the information source stored in the remote database remains static until the user manually updates the information source. Furthermore, the knowledge-graph information is not personal information of the user but rather information about world entities in general. Also, the information identified may not be locally relevant to user query or do not take current user context (location) and user knowledge into account.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

In an embodiment of the present disclosure, the controlling module 206 can be configured to determine the user activity performed on the electronic device 102.

For example, the user activity can be a browsing activity, specifying a query, a selection activity, a hovering activity or the like. For example, specifying a query includes providing a query regarding gestational diabetes or any other information required by the user 104.

Based on the user's activity determined by the controlling module 206, the method 700 allows the data analyzer module 201 to extract one or more items from the data and the semantic analyzer module 202 to determine semantically correct keywords from the extracted items. Further, the method 700 allows the controlling module 206 to send the extracted items and keywords to the server 105 for interpreting a query or building a localized query on the server 105. For example, the extracted items from the browser application can be keywords such as songs, actors, director, music composer, producer or the like. Further, based on the extracted keywords, the server 105 can determine the localized query such as “Need information about films”, or “Need information about Bollywood” or the like.

At operation 702, the method 700 includes receiving a localized query at one or more information sources 101. In an embodiment of the present disclosure, the method 700 allows the controlling module 206 to receive the localized query from the server 105 on to one or more information sources 101 within the assistive network 100.

At operation 703, the method 700 includes computing a semantic similarity between the determined intent and a knowledge graph of the information source 101. In an embodiment of the present disclosure, the method 700 allows the controlling module 206 to compute a semantic similarity between the determined intent (captured in the form of the localized query and sent by the server 105) and the knowledge graph stored in one or more information sources 101. For example, the localized query sent from the server 105 “Need information about films” can be used to determine the intent and further the semantic similarity is computed between the determined intent and the information stored in the knowledge graph on one or more information sources 101.

At operation 704, the method 700 includes sending the one or more information source data from the one or more information sources 101 to the server 105. In an embodiment of the present disclosure, the method 700 allows the controlling module 206 to send one or more information source data from one or more information sources 101 to the server 105 based on the semantic similarity determined between the localized query sent by the server 105 and the knowledge graph stored in one or more information sources 101. For example, if information source of user A and information source of user B provides information for the localized query “Need information about films” then information source data of user A and user B are sent to the server 105.

At operation 705, the method 700 includes displaying the one or more information source data to the user 104.
