Negative cost about mecab-ipadic-neologd HOT 2 CLOSED

Thank you for your frank question.

In conclusion, we think this case is correct and not a bug.
And using negative integer values in the range of 2-byte integers as a cost value conform to the IPADIC specification.

Also, the cost value given to each words are not necessarily based on the frequency of word observation in the real world or in the corpus.

Chapter 5, (P 79 -) in the following book will help you understand how different cost values are used in the analysis process.
