| After successfully completing the [[https://www.korpus.cz/toolbar/signup.php|online registration]] and logging into KonText, we can begin with our very first query in the EEBO corpus. First of all, we need to select the corpus we intend to work with. The default corpus of KonText is the //syn2015// corpus. By clicking on the icon //syn2015//, a menu appears with all of the available corpora. If we have worked with KonText before, we might also see the list of your favorite corpora located on the left side of the menu. The list of featured corpora is located on the right side. If the EEBO corpus is not included in either of the lists, we click on the icon //all corpora// and a search box will appear where we can type in a part of the name or description of the corpus we plan to work with. We type in "EEBO" and select the corpus in the dropdown menu. By clicking on the star next to the icon with the selected corpus, we can add the EEBO corpus to the list of our favorite corpora. Next time we work with KonText, the EEBO corpus will be included in the list of //my favorite corpora//. Now we can type the query in the **Query** box. | After successfully completing the [[https://www.korpus.cz/toolbar/signup.php|online registration]] and logging into [[en:manualy:kontext:index|KonText]], we can begin with our very first query in the EEBO corpus.

| It should be noted that the EEBO corpus contains approximately 730 million words and therefore the word //myriad// (with 42 occurrences) has a relative [[en:pojmy:frekvence|frequency]] of 0.05 instances per million (i.p.m.).

| ====== Query types ====== | ====== Query types ====== |
| |
| There are 6 different query types in the KonText interface (//basic, lemma, phrase, node form, character, CQL//). Each of them is suitable for different kinds of research. As the EEBO corpus is not lemmatized, it is not possible to select //lemma// as the query type. | There are 6 different query types in the KonText interface (//basic, lemma, phrase, node form, character, CQL//).

| |
| |
| ===== Query type: word Form ===== | ===== Query type: Word Form ===== |
| |
| [[en:pojmy:word|Word Form]] is one of the most user-friendly query types. With Word Form we can search in the corpus for the specific form of the query. If we type //apple// into the query line, only those occurrences of the word will appear that exactly match the query. Therefore, //Apple// with upper-case //A// will not be included in the generated results. | [[en:pojmy:word|Word Form]] is one of the most user-friendly query types.

Therefore, //Apple// with upper-case //A// will not be included in the generated results. |
| |
| The only difference between the query and the result could be letter case. The default setting for Word Form is [[wp>Case_sensitivity|case-sensitive]] which means that the results will include both lower and upper case forms, i.e. (the query results of //god// will include both //god//,//God// but also //GOD//. | The only difference between the query and the result could be letter case.

| |
| In order for the query to be [[wp>Case_sensitivity|case-sensitive]] we need to tick the box **Match case** located beneath the query line. If we enter //James// with upper-case ''J'', the concordance list will include only the exact match //James//, excluding //james//. | In order for the query to be [[wp>Case_sensitivity|case-sensitive]] we need to tick the box **Match case** located beneath the query line.

| Basic query is ideal for elementary searches which do not require a very high degree of accuracy (in many respects this query type is equivalent to the basic search engines such as google). In the case of a dictionary form (lemma), all of its possible forms are searched for. As the EEBO corpus is not lemmatized, this option is not possible. Therefore, only those forms appear in the results that absolutely match the query. | Basic query is ideal for elementary searches which do not require a very high degree of accuracy (in many respects this query type is equivalent to the basic search engines such as //google//).

| If we wish to find all of the words that contain a string of consecutive characters (e.g. a root), then this query type is the most suitable for this kind of searches.
