public CsliTopicSegmenterServiceImpl()

Method Detail

getTopicBreaks

public Set<XSDDateTime> getTopicBreaks(String meeting)

Description copied from interface: OnlineTopicSegmenterService

Computes the topic segmentation of the meeting. For OnlineTopicSegmenterService, this will necessarily be based on topic break classification. TopicSegmenterService may base the segmentation on lexical similarity or the MIT generative model depending on the config key topic.segmentation.method

Specified by:

getTopicBreaks in interface OnlineTopicSegmenterService

Specified by:

getTopicBreaks in interface TopicSegmenterService

Specified by:

getTopicBreaks in class CsliTopicSegmenterService

Parameters:

meeting - the meeting we want to segment

Returns:

the set of topic breaks

getTopicBreaksByMITSegmentation

public Set<XSDDateTime> getTopicBreaksByMITSegmentation(String meeting,
                                                        Integer numShifts)

Description copied from class: CsliTopicSegmenterService

Like getTopicBreaks(), but force Stephane's lexical similarity method.

Specified by:

getTopicBreaksByMITSegmentation in class CsliTopicSegmenterService

Parameters:

meeting - the meeting we want to segment

numShifts - if > 0, the fixed number of shifts required; if = 0, fix the number of shifts at the average; if < 0, use the average probability threshold

Returns:

the set of topic breaks

See Also:

getTopicBreaks()

getTopicBreaksByWordDistribution

public Set<XSDDateTime> getTopicBreaksByWordDistribution(String meeting)

Description copied from class: CsliTopicSegmenterService

Like getTopicBreaks(), but force Stephane's lexical similarity method.

Specified by:

getTopicBreaksByWordDistribution in class CsliTopicSegmenterService

Parameters:

meeting - the meeting we want to segment

Returns:

the set of topic breaks

See Also:

getTopicBreaks()

csliGetTopics

public ArrayList<Pair<Topic,TopicArea>> csliGetTopics(String meeting)

Description copied from class: CsliTopicSegmenterService

Get the Topics discussed in a meeting (using the default method), before adding to/merging with the pool

Specified by:

csliGetTopics in class CsliTopicSegmenterService

Returns:

a list of Pairs of Topic and TopicArea

csliGetTopicsByWordDistribution

public ArrayList<Pair<Topic,TopicArea>> csliGetTopicsByWordDistribution(String meeting)

Description copied from class: CsliTopicSegmenterService

Get the Topics discussed in a meeting (forcing Stephane's lexical similarity method), before adding to/merging with the pool

Specified by:

csliGetTopicsByWordDistribution in class CsliTopicSegmenterService

Returns:

a list of Pairs of Topic and TopicArea
