From Roberts and Egg (2014)[1]: "Selectional preferences (Katz and Fodor, 1963; Wilks, 1975[2]; Resnik, 1993[3]) are the tendency for a word to semantically select or constrain which other words may appear in a direct syntactic relation with it." In case this selection is expressed in binary term (allowed/not-allowed), it is also called selectional restriction (Séaghdha and Korhonen, 2014)[4]. SP can be contrasted with verb subcategorization "with subcategorization describing the syntactic arguments taken by a verb, and selectional preferences describing the semantic preferences verbs have for their arguments" (Van de Cruys et al., 2012)[5]

## Approaches Edit

### Classified based on granularity Edit

From Zapirain et al. (2013)[6]: "In one extreme, we would have a small set of coarse semantic classes. For instance, some authors have used the 26 so-called “semantic fields” used to classify all nouns in WordNet (Agirre, Baldwin, and Martinez 2008; Agirre et al. 2011). The classification could be more fine-grained, as defined by theWordNet hierarchy (Resnik 1993b; Agirre and Martinez 2001; McCarthy and Carroll 2003), and other lexical resources could be used as well. Other authors have used automatically induced hierarchical word classes, clustered according to occurrence information from corpora (Koo, Carreras, and Collins 2008; Ratinov and Roth 2009). On the other extreme, each word would be its own semantic class, as in the lexical model, but one could also model selectional preference using distributional similarity (Grefenstette 1992; Lin 1998; Pantel and Lin 2000; Erk 2007; Bergsma, Lin, and Goebel 2008)."

#### Cluster-based (using WordNet) Edit

"Resnik (1996)[7] relies on WordNet synsets in order to generate gener- alized noun clusters. The selectional preference strength of a specific verb v in a particular relation is calculated by computing the Kullback-Leibler divergence between the cluster distribution of the verb and the prior cluster distribution."

$S_{R(v)} = \sum_{c} p(c|v) \log \frac{p(c|v)}{p(c)}$

"where c stands for a noun cluster, and R stands for a given predicate-argument relation. The selectional association of a particular noun cluster is then the contribution of that cluster to the verb’s preference strength."

$A_{R(v,c)} = \frac{p(c|v) \log \frac{p(c|v)}{p(c)}}{S_{R(v)} }$

"The model’s generalization relies entirely on WordNet, and there is no generalization among the verbs."

"Li and Abe (1998) use the principle of Minimum Descrip- tion Length in order to find a suitable generalization level within the lexical WordNet hierarchy. A same intuition is used by Clark and Weir (2001), but they use hypothesis testing instead to find the appro- priate level of generalization. A recent approach that makes use of WordNet (in combination with Bayesian modeling) is the one by O ́ Se ́aghdha and Korhonen (2012)."

#### Cluster-based (using corpus) Edit

"Rooth et al. (1999)[8] propose an Expectation-Maximization (EM) clustering algorithm for selectional preference acquisition based on a probabilistic latent variable model. The idea is that both predicate v and argument o are generated from a latent variable c, where the latent variables represent clusters of tight verb-argument interactions."

$p(v,o) = \sum_{c \in C} p(c,v,o) = \sum_{c \in C} p(c) p(v|c) p(o|c)$

### Classified based on model structure/algorithm Edit

TODO: From Zapirain et al. (2013): "More recent work on distributional selectional preference has explored the use of discriminative models (Bergsma, Lin, and Goebel 2008) and topical models (O Seaghdha 2010; Ritter, Mausam, and Etzioni 2010)."

#### Language modeling Edit

"It is tempting to assume that with a large enough corpus, preference learning reduces to a simple language modelling task that can be solved by counting predicate-argument co-occurrences. Indeed, Keller and Lapata (2003) show that relatively good performance at plausibility estimation can be attained by submitting queries to a Web search engine."

"O Seghdha (2010) shows that the Web-based approach is reliably outperformed by more complex models trained on smaller corpora for less frequent predicate-argument combinations."

#### Analogical reasoning (examplar-based) Edit

"Erk (2007)[9] and Erk et al. (2010)[10] describe a method that uses corpus-driven distributional similarity metrics for the induction of selectional preferences. The key idea is that a predicate-argument tuple (v,o) is felicitous if the predicate v appears in the training corpus with arguments o′ that are similar to o, i.e."

$S(v,o) = \sum_{o' \in O_v} \frac{wt(v, o')}{Z(v)} \cdot sim(o, o')$

#### Linear classification Edit

Bergsma et al. (2008)[11]: SVM

#### Neural network Edit

Van de Cruys (2014)[12]

#### Tensor factorization Edit

Van de Cruys et al. (2012) use 12-mode tensors to encode selectional preferences (and verb subcategorization). Each mode contains a different grammatical relation. TODO: how did they encode SP which is essentially semantic then?

## Evaluation Edit

### Pseudo-disambiguation task (Rooth et al., 1999) Edit

From Van de Cruys (2014)[12]: "The task provides an adequate test of the generalization capabilities of our models. For the two-way case, the task is to judge which object (o or o′) is more likely for a particular verb v, where (v, o) is a tuple attested in the corpus, and o′ is a direct object randomly drawn from the object vocab- ulary. The tuple is considered correct if the model prefers the attested tuple (v,o) over (v,o′). For the three-way case, the task is to judge which subject (s or s′) and direct object (o or o′) are more likely for a particular verb v, where (v, s, o) is the attested tuple, and s′ and o′ are a random subject and object drawn from their respective vocabularies. The tuple is considered correct if the model prefers the attested tuple (v,s,o) over the alternatives (v,s,o′), (v,s′,o), and (v,s′,o′). Tables 1 and 2 respectively show a number of examples from the two-way and three-way pseudo-disambiguation task."

There doesn't seem to be a standardized dataset for this evaluation. Van de Cruys (2014) created his own dataset from UkWaC (2 billion words)[13] and didn't publish the tuples. It should be noted that although SP should be about semantic preference, he created tuples from syntactic (dependency) relations.

### Semantic role classification task Edit

Zapirain et al. (2013)[6]: "SP models will be used in isolation, according to the classification rule in Equation (11), to predict role labels for a set of (predicate, argument-head) pairs."

TODO: can I find it online?

### Evaluate against human plausibility judgment Edit

"This is a standard approach to selectional preference evaluation (Keller and Lapata, 2003; Brockmann and Lapata, 2003; O ́ Se ́aghdha, 2010) and arguably yields a better appraisal of a model’s intrinsic semantic quality than other evaluations such as pseudo-disambiguation or held-out likelihood prediction."

However, it isn't clear what does it mean by plausible. In Keller and Lapata (2003)[14], "the concept of plausibility was not defined, but examples of plausible and implausible bigrams were given (different examples for each stimulus set)."

#### Keller and Lapata (2003) Edit

"... a set of plausibility judgements collected by Keller and Lapata (2003)[14]. This dataset comprises 180 predicate-argument combinations for each of three syntactic relations: verb-object, noun-noun modification and adjective-noun modification. The data for each relation is divided into a “seen” portion containing 90 combinations that were observed in the British National Corpus and an “unseen” portion containing 90 combinations that do not appear (though the predicates and arguments do appear separately).

Some methods have reached the upper bound of this dataset.[15]

## Application Edit

• Word sense disambiguation (Resnik 1993a; Agirre and Martinez 2001; McCarthy and Carroll 2003),
• pronoun resolution

(Bergsma, Lin, and Goebel 2008

• Metaphor processing (Shutova et al., 2013)
• named-entity recognition (Ratinov and Roth 2009)
• Information extraction: "improve the quality of inference and information extraction rules" (Pantel et al. 2007;
• Textual inferecne: Ritter, Mausam, and Etzioni (2010; Section 4.3)[16]

### Parsing Edit

Hindle 1990; Resnik 1993b; Pantel and Lin 2000; Agirre, Baldwin, and Martinez 2008; Koo, Carreras, and Collins 2008; Agirre et al. 2011), Zhou et al., (2011)[17], Mirroshandel et al. (2016) [18]

### Semantic role labeling Edit

TODO: (Gildea and Jurafsky, 2002), (Zapirain et al., 2009)[19] (Zapirain et al., 2010)[20]

(Gildea and Jurafsky, 2002),

Zapirain et al. (2013)[6] use directly a SP model in semantic role classification (i.e. the step after argument identification):

$ROLE(p,w) = \arg \max SP(p, r, w)$

They propose special treatment for prepositional arguments which is very important for this task.
