Unsupervised Morphological Segmentation Based on Segment Predictability and Word Segments Alignment

Word segments are relevant cues for the automatic acquisition of semantic relationships from morphologically related words. Indeed, morphemes are the smallest meaning-bearing units. We present an unsupervised method for the segmentation of words into sub-units devised for this objective. The system relies on segment predictability to discover a set of prefixes and suffixes and performs word segments alignment to detect morpheme boundaries.
