Information Retrieval with Conceptual Graph Matching
نویسندگان
چکیده
The use of conceptual graphs for the representation of text contents in information retrieval is discussed. A method for measuring the similarity b etween two texts represented as conceptual graphs is presented. The method is based on well-known strategies of text comparison, such as Dice coefficient, with new elements introduced due to the bipartite nature of the conceptual graphs. Examples of the representation and comparison of the phrases are given. The structure of an information retrieval system using two-level docu ment representation, trad itional keywords and conceptual graphs, is presented.

Flexible Comparison of Conceptual Graphs
Conceptual graphs allow for powerful and computationally affordable representation of the semantic contents of natural language texts. We propose a method of comparison (approximate matching) of conceptual graphs. The method takes into account synonymy and subtype/supertype relationships between the concepts and relations used in the conceptual graphs, thus allowing for greater flexibility of a...
متن کاملIncomplete and Fuzzy Conceptual Graphs to Automatically Index Medical Reports
Most of Information Retrieval (IR) systems are still based on bag of word paradigm. This is a strong limitation if one needs high precision answers. For example, in restricted domain, like medicine, user builds short and precise query, like “Show me chest CT images with emphysema.”, and expects from the system precise answers. In such a case, the use of natural language processing to model docu...
متن کاملA New Question Answering Approach with Conceptual Graphs
With the increasing availability of large-scale structured knowledge bases and natural language processing (NLP) techniques aided by advanced information retrieval (IR) techniques, question answering (QA) systems have entered into a commercialization era. However, the types of questions that can be answered are somewhat limited to encyclopedic knowledge that are often either well structured lik...
متن کاملSpontaneous Retrieval in a Conceptual Information System
A traditional paradigm for retrieval from a conceptual knowledge base is to gather up indices or features used to discriminate among or locate items in memory, and then perform a retrieval operation to obtain matching items. These items may then be evaluated for their degree of match against the input. This type of approach to retrieval has some problems. It requires one to look explicitly for ...
متن کاملImproved Skips for Faster Postings List Intersection
Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...
