A method, apparatus and computer program product for presenting a user interface for a conversational system is described. A user input is received in a dialog between a user and the conversational system, the user input in a natural language. A domain trained semantic matcher is used to determine a set of entities and a user intent from the user input. One or more queries is generated to selected ones of a plurality of knowledge sources, the knowledge sources created from domain specific knowledge. The results from the one or more queries are ranked based on domain specific knowledge. A system response is presented in the dialog based on at least a highest ranked result from the plurality of knowledge sources.

A method, apparatus and computer program product for creating a dialog system for web content is described. Knowledge is extracted from a target web application for the dialog system.

A plurality of knowledge sources of different respective types are created from the domain knowledge and the organizational structure. Each of the knowledge sources is used for providing answers to user queries to the dialog system. As part of the invention, a semantic matcher is provided to select among the answers provided by the plurality of knowledge sources for a best answer to a user query.

The invention provides an entity expanding method of a network list. The method comprises the steps of selecting seed lists to seed groups by calculating a semantic matching value between the networklist and a query list; selecting the group list with the maximum list potential to add into the seed groups, wherein the group list and the seed groups accord with consistency matching relations and are used for rising the coverage rate of the seed groups, and when the coverage rate reaches a set threshold value, the seed groups are considered as consistency groups meeting the given coverage rate;when nodes of the consistency groups are regarded as an answer list needed by entity expansion, using the answer list to establish a final event list expanding the entity consistency. Searching for answers, the entity expanding method of the network list brings in a concept of a consistency matching relation, the consistency of the answer list is improved, and therefore the expansion of multiplesearching lists can be adapted, so that the result consistency is guaranteed, and at the same time, the high-precision and reliability of the result are also ensured.

During operation, the system obtains a first embedding produced by an embedding model from an input string representing an entity and a hierarchy of clusters of embeddings generated by the embedding model from a set of standardized entities. Next, the system searches the hierarchy of clusters for a subset of the embeddings that are within a threshold proximity to the first embedding in a vector space. The system then calculates embedding match scores between the input string and a first subset of the standardized entities represented by the subset of the embeddings based on distances between the subset of the embeddings and the first embedding in the vector space. Finally, the system modifies, based on the embedding match scores, content outputted in response to the input string within a user interface of an online system.
