Corpora, i.e. collections of linguistic data (texts or conversations), are a fundamental asset of digital humanities research. A ubiquitous task for linguists is to explore linguistic questions in corpora: Which forms of the verb *to be* occur in a given text? Is it common that number words are preceded by articles? What types of phrase do occur as direct object in philosophical texts? What kinds of speech acts occur in modern conversations? What words can occur as hesitation markers in spoken modern German? Are texts by women longer (or shorter) than texts by men? To answer such questions, it is necessary to select and prepare data. We will discuss different approaches to compilation and annotation of corpora. Linguistic questions can only be approached if an adequate selection of texts is available; for instance, one will not find such evidence about conversational data in parliament speeches or mathematical papers. Hence, we will first be concerned with criteria and methods for compiling corpora: selecting texts based on extra- and intralinguistic criteria, including property rights. Linguistic data must be described by metadata, so that one can find e.g. utterances by female native speakers of Southern German in the second half of the 20th century about political developments in an informal setting. Approaches to metadata will be explored. It is often useful to annotate linguistic data with respect to: pragmatic structure such as speech acts or rhetorical relations; semantic elements, e.g. named entities or points in time; syntactic structures, e.g. dependencies or phrases; or morphological relations, e.g. by assigning parts of speech (*verb*, *noun*) or lemmatizing (reducing *lemmatizing* to *lemmatize*). Some of these annotations can be carried out (partly) automatically. We will discuss what tools exist and are available. The course will be mainly concerned with textual corpora, but as searching on speech or multimodal corpora is generally carried out on the transcription and annotation layers, it will also be useful to researchers dealing with such data.
