Selection of Passages for Information Reduction
Information Retrieval (IR) typically retrieves entire documents in
response to a user's information need. However, many times a user
would prefer to examine smaller portions of a document. One example
of this is when building a frame-based representation of a text. The
user would like to read all and only those portions of the text that
are about predefined important features.
This research addresses the problem of automatically locating text
about these features, where the important features are those defined
for use by a case-based reasoning (CBR) system in the form of features
and values or slots and fillers.
To locate important text pieces we gathered a small set of
``excerpts'', textual segments, when creating the original case-base
representations. Each segment contains the local context for a
particular feature within a document. We used these excerpts to
generate queries that retrieve relevant passages. By locating
passages for display to the user, we winnow a text down to sets of
several sentences, greatly reducing the time and effort expended
searching through each text for important features.
