Joint pretraining models, on the one hand, augment distributional LM objectives with additional objectives based on external resources (Yu and Dredze, 2014; Nguyen et al., 2016; Lauscher et al., 2019) and train the extended model from scratch. For models like BERT, this implies computationally expensive retraining from scratch of the encoding transformer network. Post-hoc fine-tuning models (Zhang et al., 2019; Liu et al., 2019a; Peters et al., 2019) , on the other hand, use the objectives based on external resources to fine-tune the encoder's parameters, pretrained via distributional LM objectives.

| "text": "In this work, similar to the concurrent work of Wang et al. (2020) , we turn to the recently proposed adapter-based fine-tuning paradigm (Rebuffi et al., 2018; Houlsby et al., 2019) , which remedies the shortcomings of both joint pretraining and standard post-hoc fine-tuning. Adapterbased training injects additional parameters into the encoder and only tunes their values: original transformer parameters are kept fixed. Be-cause of this, adapter training preserves the distributional information obtained in LM pretraining, without the need for any distributional (re-)training. While (Wang et al., 2020) inject factual knowledge from Wikidata (Vrande\u010di\u0107 and Kr\u00f6tzsch, 2014) into BERT, in this work, we investigate two resources that are commonly assumed to contain generalpurpose and common sense knowledge: 1 Concept-Net (Liu and Singh, 2004; Speer et al., 2017) and the Open Mind Common Sense (OMCS) corpus (Singh et al., 2002) , from which the ConceptNet graph was (semi-)automatically extracted. For our first model, dubbed CN-ADAPT, we first create a synthetic corpus by randomly traversing the Con-ceptNet graph and then learn adapter parameters with masked language modelling (MLM) training (Devlin et al., 2019) on that synthetic corpus. For our second model, named OM-ADAPT, we learn the adapter parameters via MLM training directly on the OMCS corpus.", | |

However, a more detailed inspection reveals large improvements over the base BERT model (up to 20 Matthews correlation points) on language inference (NLI) subsets labeled as requiring World Knowledge or knowledge about Named Entities. Investigating further, we relate this result to the fact that ConceptNet and OMCS contain much more of what in downstream is considered to be factual world knowledge than what is judged as common sense knowledge. Our findings pinpoint the need for more detailed analyses of compatibility between (1) the types of knowledge contained by external resources; and (2) the types of knowledge that benefit concrete downstream tasks; within the emerging body of work on injecting knowledge into pretrained transformers.", | |

We inject the external information into adapter parameters of the adapter-augmented BERT (Houlsby et al., 2019 ) via BERT's natural objective -masked language modelling (MLM).

To investigate this further, we measure the model performance across different categories of the Diagnostic NLI dataset. This allows us to tease apart inference instances which truly test the efficacy of our knowledge injection methods. We show the results obtained on different categories of the Diagnostic NLI dataset in Table 2 . The improvements of our adapter-based models over BERT Base on these phenomenon-specific subsections of the Diagnostics NLI dataset are generally much more pronounced: e.g., OM-ADAPT (25K) yields a 7% improvement on inference that requires factual or common sense knowledge (KNO), whereas CN-ADAPT (100K) yields a 6% boost for inference that depends on lexico-semantic knowledge (LS). These results suggest that (1) ConceptNet and OMCS do contain the specific types of knowledge required for these inference categories and that (2) we managed to inject that knowledge into BERT by training adapters on these resources.", | |

In our final analysis, we \"zoom in\" our models' performances on three fine-grained categories of the Diagnostics NLI dataset -inference instances that require Common Sense Knowledge (CS), World Knowledge (World), and knowledge about Named Entities (NE), respectively. The results for these fine-grained categories are given in In contrast, many of the CS inference instances require complex, high-level reasoning, understanding metaphorical and idiomatic meaning, and making far-reaching connections. We display NLI Dignostics examples from the World Knowledge and Common Sense categories in Table 4 . In such cases, explicit conceptual links often do not suffice for a correct inference and much of the required knowledge is not explicitly encoded in the external resources. Consider, e.g., the following CS NLI instance: [premise: My jokes fully reveal my character ; hypothesis: If everyone believed my jokes, they'd know exactly who I was ; entailment]. While ConceptNet and OMCS may associate character with personality or personality with identity, the knowledge that the phrase who I was may refer to identity is beyond the explicit knowledge present in these resources. This sheds light on the results in Table 3 : when the knowledge required to tackle the inference problem at hand is available in the external resource, our adapter-based knowledge-injected models significantly outperform the baseline transformer; otherwise, the benefits of knowledge injection are neg-", | |

We demonstrated the effectiveness of these models in language understanding settings that require precisely the type of knowledge that one finds in ConceptNet and OMCS, in which our adapter-based models outperform BERT by up to 20 performance points. Our findings stress the importance of having detailed analyses that com-pare (a) the types of knowledge found in external resources being injected against (b) the types of knowledge that a concrete downstream reasoning tasks requires.
