Salience Constructor

Summary

The constructor instantiates a Salience object which provides access to document-level API functionality. For collection-level functionality, a SalienceCollection object should be instantiated.

The constructor provides a wrapper around the underlying C API methods lxaLoadLicense and lxaOpenSalienceSession.

Syntax

Salience(string sLicensePath, string sDataPath)

Salience(string sLicensePath, string sDataPath, string sUserDir)

Salience(string sLicensePath, string sDataPath, string sUserDir, string sLogPath)

Salience(string sLicensePath, string sDataPath, string sUserDir, string sLogPath, SALIENCE_MODE nSalienceMode)

Salience(string sLicensePath, SalienceStartup oStartup)

Parameters

Returns

If successful, the constructor returns a Salience object that can be used for processing text. Otherwise, an exception is thrown with information about the failure of the constructor.

Example

//The SalienceEngine object wraps all of the Salience functionality 
        //and must be initialized to use the library.
        Salience Engine = null;
    
        //If this application will be run on multiple machines, it may be helpful to read these paths 
        //from a configuration file or a registry key to avoid introducing dependencies on where the 
        //license and data must be installed.
        string licensePath = "C:/Program Files/Lexalytics/License.v5";
        string dataPath = "C:/Program Files/Lexalytics/data";
    
        try
        {
            //We declared Engine before initializing it so we could put this in a try/catch block, and 
            //have the rest of the code outside.
            Engine = new Salience(licensePath, dataPath);
        }
        catch (SalienceException e)
        {
            /*If the SalienceEngine constructor throws an error, one of these is likely to be true:
             * 1) The license file is missing/invalid/out of date
             * 2) The data directory was missing or contained incorrect files
             * 3) Salience6.dll could not be found. */
            System.Console.WriteLine("Error Loading SalienceEngine: " + e.Message);
            return;
        }

Summary

This method is used to apply different sentiment hand-score dictionaries (HSDs) to the sentiment analysis of documents.

Note that this method has been carried over from the .Net wrapper for Salience 4.4. The Salience 6 C API has replaced the previous underlying method with options, which that wrapper method sets appropriately.

Salience.CorrectOCRErrors

Summary

Corrects likely OCR errors found in prepared text. This function is useful when processing scanned documents that that have been converted to electronic format through optical character recognition; there is no need to call it if the document originated from an electronic format (word processing, web page, tweet, etc.). If used, it should called after calling text preparation functions (PrepareText and PrepareTextFromFile), but before any text analytics functions (that is, any of the other functions that are typically called after preparing text).

This method is a a wrapper around the underlying C API method lxaCorrectOCRErrors.

Syntax

public string CorrectOCRErrors(List<SalienceOCRCharacterAttribute> vAttributes, float fConfidenceThreshold)

Parameters

Returns

If successful, the a corrected text string is returned. Otherwise, an exception is thrown with information about the failure of OCR correction.

Notes

When the argument vAttributes is an empty list, this function will check every character in the document to determine whether it needs to be corrected. However, some OCR engines produce confidence information about confidence information for characters that they believe might have been misrecognized. If this information is available, you can pass this information along in the the vAttributes argument along with a confidence cutoff in fConfidenceThreshold. In this case, only those characters identified in vAttributes whose confidence values fall below fConfidenceThreshold will be corrected. This will speed up the OCR error correction process.

Example

//The SalienceEngine object wraps all of the Salience functionality 
        //and must be initialized to use the library.
        Salience Engine = null;
    
        //If this application will be run on multiple machines, it may be helpful to read these paths
