Ulrich Gaudenz Müller (born October 18, 1922 in Winterthur ; † April 2005 in Zurich-Höngg) is a Swiss pioneer in computational linguistics . Together with the German and computational linguist Raimund Drewek , they succeeded in developing a system for text generation , called SARA (sentence random generator), between 1981 and 1999 .

Life

After attending primary and cantonal school (grammar school), the Matura (Abitur) passed in 1941 at the cantonal school in Winterthur, he began studying medicine in Zurich and Geneva. In 1947 Gaudenz passed the federal state examination in Zurich and then worked as an assistant doctor with training in psychiatry, surgery and gynecology . The dissertation with Manfred Bleuler , Psychiatric University Clinic Zurich from 1950 reads Healthy families of schizophrenics in the Rorschach experiment . Since 1954 he has had his own practice in Zurich (-Altstetten) as a specialist FMH for gynecology and obstetrics. In 1973 he began studying Egyptology at the University of Zurich with Peter Kaplony, with a minor in prehistory (E. Vogt, M. Primas). At Easter 1975 he first came into contact with Raimund Drewek (computational linguist at the German Seminar of the University of Zurich) and from that year until around 1981 Gaudenz attended courses on language data processing and computational linguistics together with Guido Würth. 1977 after graduating from the Philosophical Faculty of the University of Zurich, he worked on visualization methods for numerical representation of features ("Chernoff Plot") together with Guido Würth .

In 1982 the doctorate to Dr. phil. in Egyptology with a computational linguistic study of 315 ancient Egyptian gods . From 1981 to 1999 he worked on the development of a system for generating text "Sara" in MProlog. Text production with Sara at the computer center of the University of Zurich. In 1996 he met Bernd Josef Bartolome and worked closely with him. In February 1998, he retired into private life because of the death of his wife. Several strokes with paralysis ended his active professional life. He died in April 2005 in Zurich-Höngg after a serious illness.

SARA

The SARA program uses random generators, selection matrices and a word memory on varying levels of action to produce understandable texts with tunable adjectives and semantic flow across sentences . The world knowledge of Sara, the text models and thought patterns are in multi-dimensional matrices. Sara fills the syntactic niches with randomized content for the synthetic production of texts. Sara generates modern poetry , poetry and prose. For text variations, Sara randomizes the syntax or content of the selected texts. "Artifacts from Celan to Blick" are created. Based on CAD (Computer Aided Design) , Müller calls this "poetic random system" carp (computer aided random poetry).

Sara imitates human text production; the random generator takes the place of the writer's imagination. If the syntactic niches of a celan poem are not filled with random words from the Celan lexicon but with random words from the Nietzschel lexicon, the poem remains a “Celan poem”; the syntactic structure dominates, the lexicon is colored. Sara imitates the texts empirically; controlled by the syntactic and semantic topographies of the underlying texts, it generates the randomized text variations. Sara does not stop at a mere copy of the poem, but adopts the metric structure and varies the content with the random generator . Sara creates poetry and prose with varying literary algorithms . By their nature, stereotypes are the domain of the computer.

A Sara text is created as follows: Without a computer, any text is broken down into niches; Various variations are entered into the lexicon for each niche. The Sara program fills these niches with the appropriate content using the random generator. The niche fillings, i.e. words or frames, can be provided with semantic or syntactic markers in the lexicon.
