Problem DomainUsers who do not know exactly what they are looking for in a repository, so they find it difficult to describe the topic that interests them. The program will allow such people to effectively and conveniently navigate the database, through an interactive process combining search and browse.

Page 4: Learning Content Models for Semantic Search

Current SituationExisting search engines provide powerful features to identify known documents by using a short description of their content (keywords, name of document).But what happens when the user does not know the name of the term he is looking for, or when the term the user enters has several meanings.

Page 5: Learning Content Models for Semantic Search

Proposed SolutionThe user can enter text (as long as he wants)

as query.Each result of the query will be labeled with

its topic.A hierarchy of the relevant topics tree will be

displayed as addition to the result.

System architecture

Page 11: Learning Content Models for Semantic Search

Main Functional RequirementsEnd users: the user enters a query in natural

language. The user gets an answer that helps him navigate and understand the structure of the corpus.

Content manager: gets new documents and add them to a repository.

Administrator: gets statistics from the use of the system, learn from them and update the hierarchical division to topics accordingly.

Page 12: Learning Content Models for Semantic Search

Main Non-Functional RequirementsThe system works interactively with the users.The inputs come from the users.At our simulation, we will use beta-users that

will use the system and will help us make it more user-friendly.

The user should understand how to use the system in 10 minutes.

The user can prepare the input in 10 seconds.The user can interpret the output in 2.5

minutes.
