| The basic output of any query is a [[en:pojmy:konkordance|concordance]], i.e. a list of all the occurrences ([[en:pojmy:token|tokens]]) matching the query, along with their text surroundings. The **Word list** function evaluates the query in such a way that the result is a list of various words ([[en:pojmy:typ|types]]), matching the query, together with their absolute [[en:pojmy:frekvence|frequency]], [[en:pojmy:arf|ARF]] or number of documents in which the wanted phenomenon occurs. In this respect, the Word list function is analogous to [[en:manualy:kontext:frekvencni_distribuce|frequency distribuction]], however its advantage is its speed and low computational complexity, because the extra step involving the concordance is not needed with the Word list. | The basic output of any query is a [[en:pojmy:konkordance|concordance]], i.e. a list of all the occurrences ([[en:pojmy:token|tokens]]) matching the query, along with their text surroundings.

| Among the output option settings we can find a selection of either the absolute [[en:pojmy:frekvence|frequency]], [[en:pojmy:arf|ARF]] or a document count. Furthermore there is also the possibility to choose a specific output attribute (or attributes). These attributes **need not be** identical to the positional attribute selected in the top section of the form, on which all the above mentioned filters are applied. This enables us to create e.g. a frequency list of all verbs by selecting the attribute [[en:pojmy:tag|tag]] in the top section, applying the condition for a verb as in [[en:seznamy:tagy#pozice_1_-_slovni_druh|V.*]] and finally by "switching" the output type to [[en:pojmy:lemma|lemma]] – an example of such a query is shown in the picture. | Among the output option settings we can find a selection of either the absolute [[en:pojmy:frekvence|frequency]], [[en:pojmy:arf|ARF]] or a document count.
