getDocumentDetails

Summary

Gets various bits of useful information about the current text including term frequency analysis and document chunk information.

This method provides a wrapper around the underlying C API method lxaGetDocumentDetails.

Syntax

salience6.getDocumentDetails(oSession, acConfigurationID)

Parameters

`oSession`	A SalienceSession object previously created via opensession
`acConfigurationID`	An identifier for a configuration added through addConfiguration, or empty string for default configuration

Returns

If successful, returns a Python dictionary containing with the following keys:

`document_terms`	A list of tokens contained with the document and their term frequencies
`fingerprint`	A string containing the calculated fingerprint of the document (DEPRECATED)
`internal_version`	A string providing the internal Salience representation of the document after preprocessing
`sentences`	A list of the individual sentences in the document, where each sentence item contains a structure of information about the sentence.
`sentence_count`	An integer giving the count of sentences in the document
`word_count`	An integer giving the count of words in the document

Example

    ret = se6.prepareTextFromFile(session,'/path/to/aFile.txt')
    if (ret==0):
        details = se6.getDocumentDetails(session,"")
        print details

The default summary method determines the most significant fragments in the document, and extracts the first sentence from those fragments. The alternate method extracts sentences that connect the most fragments.

This method provides a wrapper around the underlying C API method lxaGetSummary.

Syntax

salience6.getSummary(oSession, nLength, acConfigurationID)

Parameters

`oSession`	A SalienceSession object previously created via opensession
`nLength`	Maximum number of sentences for the summary
`acConfigurationID`	An identifier for a configuration added through addConfiguration, or empty string for default configuration

Returns

If successful, returns a Python dictionary containing with the following keys:

`summary`	The default summary of the document
`sentences`	Information for the individual sentences in the default summary, including ranking of importance in the summary
`alternate_summary`	An alternate summary of the document
`alternate_sentences`	Information for the individual sentences in the alternate summary, including ranking of importance in the summary

Example

import salience6 as se6
    session = se6.openSession('/path/to/license.v5','/path/to/data')
    ret = se6.prepareTextFromFile(session,'/path/to/aFile.txt')
    if (ret==0):
        summary = se6.getSummary(session, 3, "")
        print summary.

getDocumentSentiment

Summary

Returns sentiment analysis of the document text. This consists of results for phrase-based and model-based sentiment analysis.

This method provides a wrapper around the underlying C API method lxaGetSentiment.

Syntax

salience6.getDocumentSentiment(oSession, acConfigurationID)

Parameters

`oSession`	A SalienceSession object previously created via opensession

`models`	A list of model-based sentiment results, where each item contains a structure of information about sentiment analysis based on a specific model found in the data directory

The DocumentSentiment object returned by GetDocumentSentiment has a getSentimentScore() function, and a getSentimentPhrases() function returning a vector of SentimentPhrases. The former is mostly an average of the scores of the latter.

Example

import salience6 as se6
    session = se6.openSession('/path/to/license.v5','/path/to/data')
