About ForFun

ForFun is

PDTs are four available Prague dependency treebanks of Czech texts. ForFun is a place where all of their sentences can be browsed in a user-friendly way.

Purpose of ForFun

If the relation between form and function is of an importance for you, the purpose of the ForFun database is to serve you!

The form–function relation is a many-to-many relation. One surface form (let say a preposition po + locative case or an infinitive) can represent several linguistic functions (e.g. time expression or location). And vice versa, one function can be expressed by many (sometimes synonymous) forms.

Functions in ForFun

The list of functions was developed many years ago and we used it without a change. The name for a deep syntactic function of an element in a sentence in PDTs is a functor. There are several functors for causal modifications, four functors for spatial modifications, many functors for time modifications, and of course, five prominent functors for arguments. Their names (such as MEANS, COND, LOC, TWHEN or ACT) indicates their meanings, however the full list is useful.

Use ForFun

You can start by clicking through the ForFun yourself.

If you are interested in the relation from form to function, start with the left button above and choose any Czech form in the long list (1469 items). There are cases (denoted by #-mark and a number), prepositional cases, relative clauses with a specified conjunction, infinitive verbal phrases and many others. There are also some multiword forms (e.g. secondary prepositions) with an underscore instead of a space. By choosing one form, you obtain a new page with all functions the form can represent. There is one table for each functor used, most frequent functor being the first, with a frequency number specified for each of them. The table is then sorted by the word class of the governing node in a dependency syntax.

Otherwise click on the right button “From function to form” above. Then you can choose any of 66 functors used in PDTs to explore their realization in sentences. You obtain a new page with all forms representing the chosen functor. There is one table for each word class that can govern the functor in a dependency syntax. The most frequent word classes are at the top, their frequency is always provided. Inside the table there are all possible forms for the functor, again with their absolute frequency.

No matter from which side (form or function) you come to the table, there are many example sentences for the form–function relation. These sentences are further divided by their source treebank. (PDT consists of newspapers, PCEDT consists of translations from an English journal, PDTSC consists of spoken data and FAUST consists of text fragments from web.) The set of sentences for a given form, function, governing word class and source is called a 4‑combination.

There is a “show” button for each 4‑combination that shows at most ten examples on demand. If you need all examples (sometimes tens of thousands), click on the other “show all exam.” to get a new page. Each example can be removed from the view using an X-button at the right. The word of the studied form and representing the studied function is highlighted together with its auxiliary words if any. At the end of the sentence, the word is repeated and its lemmatized variant is added.

At the top of each page a set of buttons allows you to hide some 4‑combinations according to their source. Examples of usage:

You can jump from forms to functions anytime you click on a name of a functor. And vice versa, you can always click on a form to explore the form–function relation from the opposite side.
