Abstract: According to an aspect of an embodiment, a method of measuring physiological adaptability of a subject is described. The method may include receiving, from a first sensor, a first data signal indicating a first biological function of the subject. The method may also include receiving, from a second sensor, a second data signal indicating a second biological function of the subject. The method may also include calculating an adaptability of the subject based on the first data signal and the second data signal. The method may also include reporting the calculated adaptability.

Abstract: In one embodiment, determining a document specificity includes accessing a record that records the clusters of documents. The number of themes of a document is determined from the number of clusters of the document. The specificity of the document is determined from the number of themes.

Abstract: In certain embodiments, generating a hierarchy of terms includes accessing a corpus comprising terms. The following is performed for one or more terms to yield parent-child relationships: one or more parent terms of a term are identified according to directional affinity; and one or more parent-child relationships are established from the parent terms and each term. A hierarchical graph is automatically generated from the parent-child relationships.

Abstract: A predetermined number of temporary terms are obtained that have the highest differential affinity to each of a number of candidate terms. Each temporary term and the associated differential affinity is placed into a set of temporary terms. An average differential affinity is calculated for each temporary term of the set of temporary terms, the average differential affinity representing an average of differential affinities from the each temporary term to every term of the initial set of terms. One or more terms with an average differential affinity that fails to satisfy a predetermined threshold are removed from the temporary set. One or more terms of the temporary set with differential affinities above the threshold are placed into the set of candidate terms. One or more terms of the set of candidate terms are selected and output to a user.

Abstract: In one embodiment, assigning tags to a document includes accessing the document, where the document comprises text units that include words. The following is performed for each text unit: a subset of words of a text unit is selected as candidate tags, relatedness is established among the candidate tags, and certain candidate tags are selected according to the established relatedness to yield a candidate tag set for the text unit. Relatedness between the candidate tags of each candidate tag set and the candidate tags of other candidate tag sets is determined. At least one candidate tag is assigned to the document according to the determined relatedness.

Abstract: In one embodiment, generating an ontology includes accessing an inverted index that comprises inverted index lists for words of a language. An inverted index list corresponding to a word indicates pages that include the word. A word pair comprises a first word and a second word. A first inverted index list and a second inverted index list are searched, where the first inverted index list corresponds to the first word and the second inverted index list corresponds to the second word. An affinity between the first word and the second word is calculated according to the first inverted index list and the second inverted index list. The affinity describes a quantitative relationship between the first word and the second word. The affinity is recorded in an affinity matrix, and the affinity matrix is reported.
