Thanks &#x27;nl, &#x27;nostrademons and &#x27;rcpt for the links! I&#x27;ve been using Chronicity[0] in my project, and I hand-hacked a Polish-to-English regexp &quot;translator&quot; to make it work with Polish language[1]. I&#x27;ll be looking at the sources of the libraries you provided as well as papers they reference; maybe I&#x27;ll manage to steal some code :).<p>[0] - <a href="https:&#x2F;&#x2F;github.com&#x2F;chaitanyagupta&#x2F;chronicity" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;chaitanyagupta&#x2F;chronicity</a><p>[1] - it&#x27;s surprising how easy is to get 80% there with hacks like these: <a href="https:&#x2F;&#x2F;github.com&#x2F;TeMPOraL&#x2F;alice&#x2F;blob&#x2F;master&#x2F;language.lisp#L123" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;TeMPOraL&#x2F;alice&#x2F;blob&#x2F;master&#x2F;language.lisp#...</a>
