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             * 1) The license file is missing/invalid/out of date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;
        }

Salience.AddSalienceConfiguration

Summary

Supports the analysis of content through multiple user directories.

This method adds the specified user directory, with the customizations and tuning it contains, to the specified Salience session. After adding a configuration to the Salience session, additional processing options and results from various API methods can be retrieved by using the identifier provided in configurationID.

Calling this method with a value for configurationID that has been previously added will result in an error code returned.

Syntax

public void AddSalienceConfiguration(String userDir, String configurationID)

Parameters

Returns

Integer return code. LXA_OK indicates success, LXA_CONFIG_IN_USE indicates the provided configuration ID has already been added to the session.

Salience.RemoveSalienceConfiguration

Summary

This method removes the specified configuration from those used in processing content in the the current Salience session.

Calling this method with a value for configurationID that has not been previously added by a call to Salience.AddSalienceConfiguration will result in an error code returned. Additionally, calling this method with an empty string (which identifies the default configuration) will result in an error.

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

Syntax

public void RemoveSalienceConfiguration(String configurationID)

Parameters

Returns

Integer return code. LXA_OK indicates success, LXA_INVALID_CONFIG indicates the provided configuration ID has already been added to the session, also returned if this method is called with an empty string for configurationID.
