Fields

Modifier and Type	Field and Description
boolean	addPatWithoutPOS Add patterns without POS restriction as well: One of this and usePOS4Pattern has to be true.
int	maxWindow4Pattern Consider contexts less than or equal to these many tokens -- total of left and right contexts be can double of this.
int	minWindow4Pattern Consider contexts longer or equal to these many tokens.
int	numMinStopWordsToAdd If the whole (either left or right) context is just stop words, add the pattern only if number of tokens is equal or more than this.
boolean	useFillerWordsInPat Ignore words like "a", "an", "the" when matching a pattern.
boolean	useNextContext Consider contexts on the right of a token.
boolean	usePOS4Pattern Use POS tag restriction in the target term: One of this and addPatWithoutPOS has to be true.
boolean	usePreviousContext Consider contexts on the left of a token.

Field Detail

usePOS4Pattern

@Execution.Option(name="usePOS4Pattern")
public boolean usePOS4Pattern

Use POS tag restriction in the target term: One of this and addPatWithoutPOS has to be true.

addPatWithoutPOS

@Execution.Option(name="addPatWithoutPOS")
public boolean addPatWithoutPOS

Add patterns without POS restriction as well: One of this and usePOS4Pattern has to be true.

minWindow4Pattern

@Execution.Option(name="minWindow4Pattern")
public int minWindow4Pattern

Consider contexts longer or equal to these many tokens.

maxWindow4Pattern

@Execution.Option(name="maxWindow4Pattern")
public int maxWindow4Pattern

Consider contexts less than or equal to these many tokens -- total of left and right contexts be can double of this.

usePreviousContext

@Execution.Option(name="usePreviousContext")
public boolean usePreviousContext

Consider contexts on the left of a token.

useNextContext

@Execution.Option(name="useNextContext")
public boolean useNextContext

Consider contexts on the right of a token.

numMinStopWordsToAdd

@Execution.Option(name="numMinStopWordsToAdd")
public int numMinStopWordsToAdd

If the whole (either left or right) context is just stop words, add the pattern only if number of tokens is equal or more than this. This is get patterns like "I am on X" but ignore "on X".

useFillerWordsInPat

@Execution.Option(name="useFillerWordsInPat")
public boolean useFillerWordsInPat

Ignore words like "a", "an", "the" when matching a pattern.

useStopWordsBeforeTerm

@Execution.Option(name="useStopWordsBeforeTerm")
public boolean useStopWordsBeforeTerm

allow to match stop words before a target term. This is to match something like "I am on some X" if the pattern is "I am on X"
