Formal Concept Analysis and Information Retrieval – A Survey [chapter]

Victor Codocedo, Amedeo Napoli
2015 Lecture Notes in Computer Science  
One of the first models to be proposed as a document index for retrieval purposes was a lattice structure, decades before the introduction of Formal Concept Analysis.  ...  In the '90s, as FCA was starting to settle as an epistemic community, lattice-based Information Retrieval (IR) systems smoothly transitioned towards FCA-based IR systems.  ...  How have FCA and concept lattices been used in the context of IR applications?  ...

Analysis of a Vector Space Model, Latent Semantic Indexing and Formal Concept Analysis for Information Retrieval

Ch. Aswani Kumar, M. Radvansky, J. Annapurna
2012 Cybernetics and Information Technologies  
Mathematical lattices, under the framework of Formal Concept Analysis (FCA), represent conceptual hierarchies in data and retrieve the information.  ...  Latent Semantic Indexing (LSI), a variant of classical Vector Space Model (VSM), is an Information Retrieval (IR) model that attempts to capture the latent semantic relationship between the data items.  ...  Lattice based retrieval models are available in literature since 1960's. Mooers model is the first application of lattices in IR applications.  ...

APPLYING CONCEPT FORMATION METHODS TO SOFTWARE REUSE

ROBERT GODIN, GUY MINEAU, ROKIA MISSAOUI, MARC ST-GERMAIN, NAJIB FARAJ
1995 International journal of software engineering and knowledge engineering  
Second, the generated concepts are used in identifying new abstractions that may be converted into new more generic artifacts with better reuse potential.  ...  First, the concept hierarchy generated by the concept formation methods is used for organizing and retrieving the artifacts inside a repository.  ...  As for the retrieval application, the additional richness and refinement of the concept lattice is to consider in the light of the additional computational cost.  ...

2011 Spoken Language Understanding  
In this chapter we discuss the retrieval and browsing of spoken audio documents.  ...  by inadequate statistical models or out-of-vocabulary words.  ...  The query is generally assumed to be in the form of a string of text-based words (though spoken queries may be used instead of text in some applications).  ...

Model Driven Ramp Control at RHIC [article]

Johannes van Zeijts
2001 arXiv   pre-print
An on-line model server handles conversion to magnet strengths, and predicts the optics along the whole ramp.  ...  At the Relativistic Heavy Ion Collider (RHIC), magnets are ramped from injection energy to storage energy in several min utes where it is to remain for several hours.  ...  This application retrieves the transverse lattice functions in the transfer line and the first sextant of the rings from the model server.  ...

To support the use of this technique, a method is presented for estimating word error probability in speech recognition engines that use word graphs (lattices).  ...  The method was able to reduce the difference in retrieval effectiveness between reference texts and hypothesized texts by 13%-38% depending on the size of the document set.  ...  This research was supported in part by DARPA under research contract F33615-93-1-1330 and N00039-91-C-0158.  ...
