Title: Hierarchically Classifying Documents Using Very Few Words Authors: Hierarchically Classifying Documents Using Very Few Words
The proliferation of topic hierarchies for text documents has resulted in a need for tools that automatically classify new documents within such hierarchies. One can use existing classi ers by ignoring the hierarchical structure, treating the topics as separate classes. Unfortunately, in the context of text categorization, we are faced with a large number of classes and a huge number of relevan...
متن کاملHierarchical Facility Location and Hub Network Problems: A literature review
In this paper, a complete review of published researches about hierarchical facility location and hub network problems is presented. Hierarchical network is a system where facilities with different service levels interact in a top-down way or vice versa. In Hierarchical systems, service levels are composed of different facilities. Published papers from (1970) to (2015) have been studied and a c...

The proliferation of topic hierarchies for text documents has resulted in a need for tools that automatically classify new documents within such hierarchies. Existing classiication schemes which ignore the hierarchical structure and treat the topics as separate classes are often inadequate in text classiication where the there is a large number of classes and a huge number of relevant features ...
متن کاملHierarchically-Consistent GA Test Problems
The Building-Block Hypothesis suggests that GAs perform well when they are able to identify above-averagefitness low-order schemata and recombine them to produce higher-order schemata of higher-fitness. We suppose that the recombinative process continues recursively: combining schemata of successively higher orders as search progresses. Historically, attempts to illustrate this intuitively stra...
متن کاملHierarchically Clustered LSH for Hierarchical Outliers Detection
In this work we introduce hierarchical outliers that extend the notion of distance-based outliers for handling hierarchical data domains. We present a novel framework that permits us to detect hierarchical outliers in a consistent manner, providing a desired monotonicity property, which implies that a data observation that finds enough support so as to be disregarded as an outlier at a level of...
